15:01
MAYBE
Checking your clock…
The commute into Reforma is the real start of the pingable day in Mexico City. Before 09:00 you are writing to a train, a motorbike, or a kitchen. Traffic invents the real day. 09:30 arrivals are normal; 14:00 lunch is sacred; 19:00 replies still happen. Mexico City does not shift for daylight saving; the clock stays UTC−6 all year. If you must write outside 09:00–18:00 local, schedule send it.
